Aluminum electrolytic capacitors are the most commonly used capacitors in electronic products, and are widely used in various electronic products. EXV337M025A9PAA is a product of aluminum electrolytic capacitor. It has the advantages of high working voltage and small size, and its application field and working principle are introduced below.

Application Field

EXV337M025A9PAA aluminum electrolytic capacitors are mainly used in decoupling applications, which can act as a high-frequency filter and remove the generated high-frequency current noise. Besides, it can also be used in energy saving and surge current protection in the circuit, to maintain the stability and reliability of the control system. Moreover, they can be used in secondary power supply circuits, automatic control system circuits and broadcast diagrams.

Working Principle

The EXV337M025A9PAA aluminum electrolytic capacitors generally consists of two aluminum foil anodes, in which one of the aluminum foil is a roll-shaped and the other is an extended two-layer bar-type aluminum foil. The two aluminum foil electrodes are refined with the electrolyte liquid and are mutually wound with the trapezoid paper insulation board to form a capacitor. When the power supply is turned on, a voltage is applied between the two electrodes. During this period, the positive electrode applies a positive charge to the positive electrode, and the black charge to the negative electrode. The current flows between the two electrodes and a capacitive electric field is generated between them. So the capacitor is formed, thus performing a filtering and/or decoupling function.

Conclusion

Aluminum electrolytic capacitors are widely used in various electronic products, such as EXV337M025A9PAA. They have the advantages of high working voltage and small size. They are mainly used in decoupling applications, secondary power supply circuits, automatic control system circuits, broadcast diagrams, energy saving and surge current protection, etc. The working principle of aluminum electrolytic capacitors is that two aluminum foil electrodes are refined with the electrolyte liquid and are mutually wound with the trapezoid paper insulation board to form a capacitor, and during the process, the positive electrode applies a positive charge to the positive electrode, and the black charge to the negative electrode, thus forming a capacitor.
